Senator DI NATALE (Victoria—Leader of the Australian Greens) (12:43): I seek leave to make a short statement. The DEPUTY PRESIDENT: Leave is granted for one minute. Senator DI NATALE: I would like to respond to the statements made by Senator Roberts. Senator Roberts, if a member of your family is sick, let's hope they get better medical advice than what you have just provided— The DEPUTY PRESIDENT: Senator Di Natale, resume your seat. I remind you to direct your comments to the chair. Please continue. Senator DI NATALE: Black lung disease, or pneumoconiosis, is a grave serious condition that leads to premature death. It is the result of unregulated workplaces where individuals are exposed to occupational hazards such as coal dust and silicosis. Let's be absolutely clear here: if there is a regime in place that involves appropriate screening, appropriate monitoring—things like spirometry—we can reduce the incidence of black lung disease and other lung diseases. What we have seen is systematic failure as a result of the lack of regulation imposed by state and federal governments, where individual workers are left to the whim of these large companies, which have no regard for the health of the workers.
